Programming Glossary

This is our programming unit glossary!

Argument
An actual value (variable, constanat or declaration constant0 of a specified datatype provided when a sudprogram is called (into action); an argument lists as an ordered set of such values.
Assignment Operator (:=)
An operator which instructs the computer to store the value on its right side in the variableor declared constant whose name appears on its left side; pronounced "is assigned the value..' or "gets".
Comma(,)
symbol used to separate items in a list; good programming technique requires a blanck space after each comma.
Comment
text written for the benefit of the programmers; this text is never seem by the users of the programs.
Concatenation(+)
a binary string operator whose result is the concatenation (linking together) of the operands .
Constant
A value which never changes.
Declared Constant
A special kind of varable whose value cannot be changed once initialized(set).
Dot-Dot
option of the put keyword; instructs computer not to move te cursor to the beginning of the next line.
Function
A subprogram which returns value.
Ouput Field
the horizontal space taken by data put out by the computer; if no field width is specifies, the computer provides an output field whose length is exactly equal to the length of the data; string data are left justified and numeric data are right justified within an output field.
Ouput Field-width
For character stringsand integers, a single value is specified for the field width; for reals, two values can be specified: the overall width; 0 is a special value which specifies a field width exactly equal to the actual width of data (the defaylt width).
Parameter
A variable of a specified datatype required for the correct execution of a subprogram, a parameter lists specifies the order and dadtatypes of the values which must provide when a sudprogram is called (into action).
Percent Sign(%)
symbol used to mark the begining of a comment; the comment ends with t he line (there is no end comment symbol); % comment goes here is equivalent to < !--comment goes here-- > in HTML and /*commment goes here*/ in CSS.
Procedure
A subprogram which performs a defined task.
Put
keyword short for output; instructs computer to output objects to the run window, once the objects are output then cursor moves to the begining of the next line.
Skip
keyword used as object of put, instructs the computer to move the cursor to the begining of the next line.
Subprograms
A named program fragment.
Sequence
Unless a program specifies otherwise, the computer will execute each instruction of a program control in sequence, and all programs have at least one section of code which executes in sequence.
Variable
a named location in memory (RAM) sutable for the storage of data of a specific type: the value stored in their location can be changed, hence it's varaivle.
